For the visitors, it was a second defeat in four games and leaves them five points behind fourth-placed Tottenham, having played a game more than Klopp’s side.

“It was not enough from my team and I’m really angry because we could have got more because everybody could see in the moments we play football what could happen,” said Klopp. “We have to again accept that we didn’t play like we should. Who wants to see 90%? You can’t win a game with 90%. You need more than we did today. Two-nil? It’s deserved.”

Klopp must now reinvigorate his side before their Capital One Cup semi-final first leg tie at Stoke on Tuesday and then they travel to Exeter for Friday night’s FA Cup third-round clash.

For West Ham, a second successive win can be enjoyed before facing Wolverhampton Wanderers in the FA Cup at Upton Park on Saturday.

“There are going to be ups and downs [in the league], but when we have the majority of players fit then there are very, very few teams that are better than us on paper,” said Bilic.
